This novel arrangement is simple and effective but not exclusive of other modes of connection of either or both tension and compression members. These tension members 15 which are shown as bars, diverge from the head to points in advance of it, op-. posite to each other in the track, and adjacent the bases of the respective rails where the members deliver stress ofimpact to a metallic cross bar 21, properly positioned in the track, which extends across the track substantially in the plane of the ties and seats beneath the bases of the respective rails. The tension members 15 embrace the metallic cross bar which inthe structure illustrated passes through a closed loop 22 or hole in the front end of each tension member by which it is completely enclosed. This is far more secure than an open hook embracing the cross bar without entirely enclosing itand requires no fastening bolts or other structure to be set up at the time of installation to preclude possibility of the hook straightening out under impact. The tension member is shown as a bar having its lower end bent into a closed loop with the end ofthe bar-welded to its body at 23, but it will be apparent'that the end of the tension member need not be bent to form the hole, but that a hole may be made through the material constituting the end of the tension member. Where the tension memher is a bar having its end looped back on it self, it may be bent either forward or backward so that the body of the bar may pass over and in front of, instead of behind and under the metallic cross member. Angular spacer clips 24 are secured to the metallic cross member just inside the loops 22 of the tension members to oppose their tendency to be drawn toward each other on bumper head impact. The preferred means for positioning the ends of the metallic cross member opposite each other in the track and for main taining the bar in the desired position are those illustrated, i. e. the tension track'fixtures 25, each of which bears against the web of the rail, is bolted thereto at 26 and spiked at 27 to adjacent ties on which it seats, al-

though itmay be clamped to the rails only.

Each of these track fixtures. has means for supporting the metallic cross bar and allgning it crosswise of the track. In the construction shown this is a recess or socket 28" a formed in the body of the tension track fixture and extending endwise from its outside through the track fixture and downward from the plane of the underside of the track rail base to a point suiiiciently below the base' of the inverted cross rail to support it-ade-- quately by shoulders at each side of the recess. The track fixtures themselves might extend under the bases of the rail so that the seating of the metallic cross member on the underside of therails would be indirect. The

shape of the socket depends on the nature and cross section of the metallic cross member, which may be, as here illustrated, an inverted -lb. or heavier A. S. C. E. rail. W here the shape of the cross bar admits, meta-l may be economized and weight reduced by making the socket 28 less than a complete enclosure of the metallic cross bar, but this is a matter of choice. The term metallic cross bar is intended to be broad enough to include composite structures made up of a plurality of bars or otherwise built up, but a single inverted track rail or an I beam is preferred.
